Answer 1

15. {[23-(48:6×2-4+2):2]:2+4}:3-3=

={[23-(16-4+2):2]:2+4}:3-3=

=[(23-14:2):2+4]:3-3=

=[(23-7):2+4]:3-3=

=(16:2+4):3-3=

=(8+4):3-3=

=12:3-3=

=4-3=

=1

16. 3×{3+3×[3+3×(3+3)]+3-3²}=

=3×[3+3×(3+3×6)+3-3²]=

=3×[3+3×(3+18)+3-3²]=

=3×(3+3×21+3-3²)=

=3×(3+3×21+3-9)=

=3×(3+36+3-9)=

=3×33=

=99

17. [5×(12-2×5):2]²=

=[5×(12-10):2]²=

=(5×2:2)²=

=5²=

=25 daca se poate, imi poti da coronita pls???
